I don't know about game titles which are supported by hardware physX at present.So I dont care Nvidia or ATI running on vertual simulation softwares.
Directx 11 will provide the hardware physics acceleration flatform .Untill then there is no need for nvidia built in support.

Surely you wouldn't allow an Nvidia card to do the display when you have an ATI card on board?

That would be like pouring perfume onto dog poo.

ATI should be doing the display...

Would that demonstration be a fruit of the Lucid's Hydra chip?

I would bet on it.

Isn't it the nvidia card doing the physX and the radeon doing the display? That makes more sense and the screenshot says 'renderer radeon 3800 series''
So in that case nnvidia can crawl back into the green by selling graphics cards as addon cards instead.

Paul, think you got it wrong.

The story around is you can have an Ati running the graphics and a Nvidia card running hardware Physix acceleration.

What would be the point of using the Nvidia card in that setup otherwise? ;)

Cheers.
